麦田套种花生,由于播种期提前,生育期延长,热量条件得以改善,是有利的一面。但由于与小麦共生期增长,受小麦遮光影响较大,因而前期晚发,后期又因气温渐低而贪青。所以群体生育有前期缓升、后期缓降、中期锐增的特点。始花后80天内(麦收后的生长中期),其营养生长速度是决定总干物质积累量的关键,生殖生长速度则关系到后期产量的高低。根据这一特点,在大田管理上应着重加强前、中期肥水猛促和后期保叶防衰等措施。 Wheat field intercropping peanuts, because of the sowing period in advance, the growing period, the heat conditions can be improved, is a positive side. However, due to the increase of symbiotic period with wheat, it is greatly affected by the shading of wheat, and hence the late late onset and late greyness due to the gradual decrease of temperature. Therefore, there is a pre-population group rallies, the latter part of the slow decline, the sharp increase in the medium-term characteristics. Within 80 days after the beginning of flowering, the growth rate of vegetative growth is the key to the total dry matter accumulation, and the growth rate of reproductive growth is related to the yield of the later stage. According to this feature, in the field management should focus on strengthening the former and medium-term fertilizers and fertilizer and water conservation in the latter part of the anti-failure measures.
